As I poster earlier in the Wiki and on the list, this presents a<br>
problem for some auto-configuration of local zones which boot with<br>
DHCP and might get configuration parameters from DHCP options,<br>
such as the hostname and DNS config - but these paths in their<br>
SMF methods are cut off by checking with this routine.<br></blockquote><div><br></div><div>And there's an example - DNS config is dynamic. If you disconnect<br></div><div>from one network and connect to another, then the config changes.<br>
Even connected to the same network, it might change over time.<br>It's not just a one-time boot process.<br></div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
Can someone shed a some light on why this check is done so, and<br>
if it really needs to remain in place?<br>
<br>
In particular, it is possible to test if we are in a zone and<br>
test its IP stack type (shared or exclusive), and bail out of<br>
this test only in case of a shared-stack local zone. Is it an<br>
acceptable solutions, or are some things know/expected to break?<br>
